Hi,
Maybe it's a good idea to get an approx. system performance first for involved
hosts.
[code]
openvpn --genkey --secret /tmp/secret
time openvpn --test-crypto --secret /tmp/secret --verb 0 --tun-mtu 20000
--cipher aes-256-gcm
[/code]
3200 / execution_time_seconds ~ max. theoretical speed in Mbps.
Change --cipher aes-256-gcm to cipher used.
Ex. Laptop I currently use:
real 0m8.025s
user 0m8.089s
sys 0m0.004s
3200 / 8.096 ~ 398 Mbps
Not an exact but ballpark figure ;)
